I have a completely speculative sci-fi question I've been wrestling with, and I'd love some feedback from better minds than my own: Lets assume we develop the technology to artificially generate gravity without mass (maybe using electrogravitics). We build a spaceship that can project a gravity well at a fixed distance in front of it. This in turn pulls the ship towards the gravity well, while simultaneously moving the gravity well itself (kind of like dangling a carrot in front of a horse). 1.) Would people aboard the spaceship essentially experience free-fall (weightlessness), as they'd be constantly falling towards the gravity well but so is the ship (like being on a reduced-gravity aircraft)? On a related note: 2.) What are the effects on a human body of falling into a gravity well that is greater than 1 g, when atmosphere is removed from the equation? Let's say you're a human in a space suit and you're falling down towards a very dense rock (where the gravity is 3 g) that has no atmosphere. When you're falling, you're essentially in free-fall, so it's like your weightless. Would you have trouble with blood flow and and other issues normally associated with high g-force on the human body (such as when accelerating in a fighter jet)?
